Give me two testing types

Here are two common types of software testing, with a brief description of each:

1. Unit testing

   • Tests individual components or functions in isolation.
   • Fast to run, helps catch bugs early during development.
   • Usually written by developers and often automated (e.g., using JUnit, pytest).

2. Integration testing

   • Tests interactions between integrated components or modules.
   • Ensures different parts work together correctly (e.g., API calls, database access).
   • Can be automated or manual; sits between unit tests and system/end-to-end tests.
